So, did you read the rest of my post? I asked the same question you did - if canon has to take the rebels upscale to distance themselves from the mirrorless - what does that do to the xxD line? 7D is already a mini 1Dmkiv for less than $2k.I did, but I didn't want to leave too long a post. I think that's why we are hearing that the 7D might not get updated. In a way, Canon spread themselves too thin...too many options that are hard to differentiate and upgrade, especially with other companies pushing them. Also, the 7D is so reasonably priced for what they could have charged. I think the 70D will go back to what the 50D was, a nice body with some weather sealing, it'll have the FPS a sports guy needs, MFA, etc. And then maybe down the line Canon will push a 7Dii at a higher price point (think $2000+) with Dual Digic V and 8-10fps. But, the 5DIII can handle sports, it just lacks the APS-C reach for those lenses. Not sure how they'll handle that
What's made Canon so smart these last 6-8 months is how many people they got to buy T2i and T3i's because of sales, while Nikon sat on their defined retailer pricing. Means they can make a lot of money off lenses in the future. And right now, they are well ahead of the mirror less guys in the lens department. I know I didn't buy the A77 or NEX's (despite needing a small, light body) because my lens options were maybe 1/10th what they were for Canon.
